Hey thanks! This post of yours was incredibly useful. I went into the NIC properties to see what the Receive and Transmit buffers were set to. They were 512 and 128, respectively. I left them at those values. But then I noticed the "Speed & Duplex" setting. It was set to "Auto Negotiation". I took a chance and changed the value to "1.0 Gbps Full Duplex," ran the Internet speed test, and--voila!--the download speed shot right up to 950 Mbps. So now I have 950+ going both ways. How cool is that? Thank you for all your help. ]]> Tue, 09 May 2017 12:53:55 +0000 https://forum.asrock.com/forum_posts.asp?TID=5069&PID=28783&title=gigabit-lan-giving-me-only-600-mbps-why#28783 https://forum.asrock.com/forum_posts.asp?TID=5069&PID=28711&title=gigabit-lan-giving-me-only-600-mbps-why#28711 Author: parsec

P.S. Seems I forgot to mention this, but is important: When I run what Verizon FiOS the "Router Speed Test,"--which, I think, is the speed from the router to whatever server I'm connected to--I always get 900-1000 for both. So, it seems the problem is in fact somewhere between the desktop and the router, and that LAN Speed Test utility I ran seems to say that's it's the LAN on the motherboard itself.]]> Mon, 08 May 2017 09:47:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=5069&PID=28708&title=gigabit-lan-giving-me-only-600-mbps-why#28708 https://forum.asrock.com/forum_posts.asp?TID=5069&PID=28706&title=gigabit-lan-giving-me-only-600-mbps-why#28706 Author: coolbeans

Exactly.

Yes and yes.

I'm using the Realtek drivers I just downloaded from their website so I know they're fresh. I also have driver auto-updates in Win 10 disabled. I'll look into the diagnostics you mentioned. Also, great suggestion re: a LAN card.

Are you using ethernet cables, or MoCA ?

So your upload speed (from the PC out to the LAN or Internet) is 1000Mbps, but your download speed (from the LAN or Internet into your PC) is 600Mbps? Faster upload than download?

Normally the opposite is true, due to the ISP or the router. Upload is always slower than download, or at least I've never seen an upload rate even equal to a download rate. My upload rate is ~13% of the download rate.

Since the techs checked your connection, I assume they tested or replaced the cables running to the router? Have you tried a different cable from the router to the PC?

What about the configuration options in Device Manager for the Realtek RTL8111E NIC chip in your board? Intel NIC chip drivers have a few diagnostic tests that can be run from their Device Manager  Properties. Are you using a Realtek driver or Microsoft driver?
